I mean that I have this issue only with Android Studio (Koala and Iguana) but not Intellij IDEA Community edition. To make it 100% clear: - Android Studio (both Koala and Iguana) makes Xorg crash only with test build version 751 (and of course the currently TW xorg version) - Intellij IDEA Community edition never cause Xorg to crash I also tested Intellij IDEA because Android Studio is based on it.
